END-FACING MACHINE.

Application filed May 27, 1918.

To all whom it may concern:

Be it known that I, LUCIEN LYnoMANs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful End-Facing Machine, of which the following is a specification.

The object of this invention is to provide means for facing the abutting ends of the sections of a machine bed or the like, and particularly to provide means for facing the opposite ends of a section so that said ends shall be parallel.

In the accompanying drawings, Figure 1 is a side elevation showing an end-facing machine embodying my invention, opera.- tively mounted upon a bed section. Fig. 2

is a fragmeutal section on line 22 of Fig.

1. F ig. 3 is a top plan view ofa sub-base employed in connection with the end-facing machine. Fig. i is a sectional view taken in the plane of dotted line 11 of Fig. 3. F 5 is a view looking from the left hand end of Fig. 1.

In the drawings, (t denotes a section of the bed of a lathe, gun-boring machine or the like. The bed section a comprises carriage ways 7, each having an upper surface 9, an inner vertical surface j and an inner horizontal surface it.

1 is a sub-base comprising two portions 1 and l Fig. 3) arranged to extend longitudinally of the carriage ways f, each of said portions having on its upper side two ribs 2 on which the end-facing mechanism may be supported, and having at its outer side a longitudinal flange 3 for engagement by clamping devices on the end-facing mechanism. The sub-base is supported upon the rough unplaned ways f of the bed section by means of vertical adjusting screws 4 which extend through openings 5 in the portions 1* and 1 and bear against the upper surfaces g of the ways. The sub-base is adjusted with reference to a vertical plane by means of adjusting screws 6, which extend through horizontal openings in the longitudinal side walls 8 of a chamber or box 9 extending downwardly between the portions 1 and 1" of the sub-base. By means of the adjusting screws 1 and 6, the sub-base may be properly located upon the bed section a. Suitable means may be provided for securing the subbase to the bed section, as, for example, clamping members 10, each supported at a point between its ends by a screw 11, the

head of which screw is supported by a fork orbifurcated lug 12 on the sub-base over hanging the interior of the box 9. The outer end of each clamping member 10 is adapted to underlie the surface of the adjacent. way 7". The inner end of each clamping member is arranged to be drawn downwardly bymeans of an adjusting screw ei'igaging the bottom wall of the box 9. By

means of the screws 12 and 13 the members 10 may be clamped tightly against the surfaces is.

In practice, the bed sections of the various machines being manufactured may vary in length, and for this reason the end-facing mechanism is preferably supported upon of sub-bases are mounted upon the bed,

section a the ends of which are to be faced, and all of said sub-bases are accurately alined with reference to each other before the operation of facing the ends of the bed section is begun.

Theform of end-facing mechanism herein shown comprises a frame H adapted to rest upon the surfaces 2 of the subbases and arranged to be rigidly secured to the sub-bases by suitable means such as clamping plates 15, which are held against the lower surfaces of the flanges 3 by means of clamping bolts 16.

At one end of the frame 14 is a downwardly extending arm 17 which is spaced away from the adjacent portionof the frame to provide an open space 18. In the lower end of the arm 17 is rotatably mounted a horizontal shaft or arbor 19. The inner end of the shaft 19 is mounted in a bearing 19 (Fig. 1) secured to the frame 14. Each sub-base has a space 1 between the portions 1 and 1 so as to becapable of accommodating the bearing 19. On the shaft 19 is fixed a wheel QOarranged to revolve in the space 18 and opposite the end of the bed section a. The wheel 20 may be revolved in any suitable manner. Herein the wheel is shown as being a spur gear wheel, mesh ing with a pinion 21 on horizontal shaft 22 in the arm 17. Upon the outer end of the shaft 22 is a spur gear wheel 23 that meshes with a pinion 2a on a shaft 25 carried by the frame l t. The shaft 25 is driven from an electric motor 26 by means of intermeshing gears 27 and 27, said motor being mounted upon the frame 1%.

The cutting means may be of any suitable character. Herein I have shown two cutting tools 28, each carried by a slide 29, said slides being mounted upon a guide 30 secured to one side of the wheel 20. 31 is a rod provided with right-hand and lefthand screw-threads engaging correspondingly threaded portions .,c0nnected to the slides 29 for simultaneously moving said slides toward or away from each other. The rod 31 is arranged to be rotated by suitable means, as, for example, a star wheel 32 secured to one end of said rod and engaging a pin 33 carried by the frame of the ma chine. In each revolution of the wheel 20 the star wheel engages the pin 33 and is turned through the distance of one tooth so as to move the slides 29 toward each other, and thus carry the tools 28 across the work. The tools may be returned to starting position by manually rotating the rod 31 in the reverse direction.

One of the tools 28 may take a roughing cut and the other a finishing cut.

After one end of the bed section a has been faced, the frame 1% is unclamped from the subbases l, transferred to the opposite end of the bed section, and there clamped to the sub-bases. In this manner the opposite ends of the bed sections a are faced so as to be exactly parallel with each other.

While the invention has been herein disclosed as embodied in an end-facing machine, it will be understood that the invention may have other uses.
